(AP) - What Rapid City police believed was the city’s second homicide of the year and of a 24-hour period is now being treated as a suicide. 20-year old Michael Mayweather of Rapid City was found dead inside a home about 3:00 Wednesday afternoon with what police said in a release was an "obvious gunshot wound to the head."

With no gun near Mayweather and the house being known for drug activity, the death was investigated as a homicide but Police Chief Karl Jegeris says the investigation uncovered "complicating factors" that pointed to suicide.

Jegeris says investigators determined a resident of the house took the gun before first-responders arrived and hid it in a window well, where it was later found, and they determined Mayweather's body had been moved for medical reasons.

The Chief also says the autopsy indicates a self-inflicted gunshot wound, but that it could take several weeks or months to get the results of other tests such as gunshot residue and the death will continued to be investigated until suicide is confirmed.

Jegeris makes no apologies for the handling of the case because it's his department's responsibility to "diligently investigate the circumstances of any unattended death (which) often means treating an unattended death as a homicide until evidence gathered suggests otherwise."

Jegeris also says the the "public nature" of this shooting incident "warrants a high level of transparency into the investigation," adding that "It’s very important the community understand the often-difficult nature of the work our officers are presented with."

There have also been major developments in the week's first homicide investigation, the Tuesday evening death of 17-year-old Emmanuel Hinton of Box Elder, who was fatally shot while in a vehicle in an alley in Rapid City.

Chief Jegeris say two 19-year-old men Rapid City men have been arrested in the case and that an attempted robbery may have triggered the shooting.
